Selectmen signed off this week on the purchase and sale agreement that will create Noquochoke Village, an affordable-housing complex to be located off Route 177.

The land to be used for the 50-unit affordable-housing complex was formerly the Quinn and Perry farms.

Of the 50 units, 40 units will be reserved for those making 80 percent or less of the median income in Westport.

Selectman R. Michael Sullivan, the lone member of the Board of Selectmen to vote against the proposal, said he didn’t like the fact that the town received $750,000 from the Affordable Housing Authority for 27 acres but will collect only a $500 payment in lieu of taxes.

“I am opposed to the project as it is now structured,” Sullivan said.

“When you compare this to other residences and commercial buildings in town, it is comparable,” said Selectman Craig Dutra.

“I just think we could do better,” Sullivan said.

“I think this is a good deal for the town,” said Board of Selectmen Chairman Antone Vieira Jr.

“This is a big step toward meeting the legal requirement to provide affordable housing in Westport,” said Affordable Housing Commission Member Brian Corey.

Corey said the cost of the buildings, at $12,800 per unit, is considerably less than the $200,000 per unit the town might spend per unit if the development was built by a for-profit developer.

Noquochoke Village will be built by the Community Builders, a nonprofit development firm.

“I’d like to see the next one structured differently,” Sullivan said.

Vieira said every selectman had been diligent about looking over plans provided by the Housing Partnership.

“We all feel passionately about this, and we should,” Vieira said.

Vieira, Dutra and Selectman Richard Spirlet voted to approve the purchase and sale agreement with the Community Builders. Sullivan voted against it, and Selectman Steven Ouellette was absent.
